Dear friends,Sorry, there was a faux pas in the previous diagram.The Black knight on g6 was missing.Now it’s right there.With the knight on g6 the task looks complicated.In fact it’s easy.Here is a hint: Without the knight on g6 White mates with 1.Qc6 Rxc6 2.c5.There is one more way of doing it.It’s miraculously simple!If you find it, the same will work with the knight on g6 as well.Best of luck!
